Examples: 1. Find the measure of the complement and supplement of a 43 angle. 2. ⊥Given: ⃗⃗⃗⃗⃗ ⃗⃗⃗⃗⃗ , m 2 is three greater than twice m 1. Find the measure of each angle. 3. The measure of the supplement of an angle is 60 less than 3 times the measure of the complement of the angle.
When looking for the value of x or an angle measurement that consists of algebraic expressions in a diagram such as the ones you see on this page, you must set up an equation to answer the problem. To do this, you must know the angle relationship between the angles that you are working with.

Complementary angles are two angles whose sum of the measurements is 90°. Once an angle relationship is identified, the relationship can be modeled with an equation that will find an unknown value.
Definition In a protractor geometry {P, L, d, m}, we say ∠ABC is an acute angle if m(∠ABC) < 90, a right angle if m(∠ABC) = 90, and an obtuse angle if m(∠ABC) > 90. We say angles ∠ABC and ∠DEF are supplementary if. m(∠ABC) + m(∠DEF ) = 180. and we say angles ∠ABC and ∠DEF are complementary if. m(∠ABC) + m(∠DEF ) = 90.
Complementary angles are a pair of angles that, when added together, equal 90°. In simpler terms, if you have ∠1 and ∠2, and their measures sum up to 90°, then ∠1 and ∠2 are considered complementary. We refer to ∠1 and ∠2 as each other's complements based on this relationship.
If the hypotenuse and a leg of a right triangle are congruent to the hypotenuse and a leg of another right triangle, then the triangles are congruent. Isosceles triangle theorem. If two sides of a triangle are equal in measure, then the angles opposite those sides are equal in measure.
